What a lease variation is
Changing a Lease That Has Already Started
A lease variation is an agreed change to a lease that is already on foot. The lease continues; one or more of its terms is altered. The change is documented in a deed of variation signed by the parties, and where the lease is registered on the title, the variation is registered as well.
In New South Wales, registered leases are varied under section 55A of the Real Property Act 1900 (NSW). A variation may increase or reduce the rent, increase or reduce the period for which the lease has effect, or otherwise vary, omit or add to the provisions of the lease. What it cannot do is change the land the lease covers — a change of premises is a different document.
Most variations are agreed commercially before a lawyer is involved. The parties have already shaken hands on the new rent, the extra years, or the longer option. The legal work is making sure the deed does what the parties think it does, that the consents the register requires are in place, and that the variation is actually capable of being registered against the title.
What can be varied
The Changes a Variation Can Make
Rent, term, options, parties, security and the operating terms of the lease. The premises themselves cannot be changed by a variation.
Extending the Term
Adding years to a lease that is running, or that has recently expired, without negotiating an entirely new lease. Section 55A expressly allows the period of a registered lease to be increased by variation, which is usually the cleanest way to do it.
Extending or Varying an Option
Lengthening an option term, adding a further option, or changing the window and preconditions for exercising one. Option clauses are read strictly, so this is often the moment to fix wording that would not have worked when the tenant came to use it.
Rent, Reviews & Incentives
Increasing or reducing rent, changing the review mechanism or review dates, documenting an abatement or rent-free period, or recording an agreed incentive. Rent changes are the most common variation and the easiest to record badly.
Parties, Guarantors & Security
Adding or releasing a guarantor, changing a company party after a restructure, or adjusting the bank guarantee or security deposit. Whether an existing guarantor remains bound after a variation depends on the drafting — it is not automatic.
Permitted Use & Operating Terms
Widening or narrowing the permitted use, changing trading hours, outgoings arrangements, signage, fit-out and make-good obligations, or assignment and subletting rights as the tenant’s business changes.
What a Variation Cannot Do
It cannot change the land the lease covers. Adding a storeroom, taking a neighbouring suite or giving back part of the premises is a surrender and a new lease, not a variation — and treating it as a variation is one of the ways these documents fail at lodgement.

Get in TouchChoosing the right document
Variation, Option Exercise, or a New Lease?
Three different documents solve three different problems, and picking the wrong one is where the cost and the delay come from.
A Deed of Variation
Right where the lease continues and the parties agree to change something in it — the rent, the term, an option, the guarantors, the permitted use. The original lease stays alive and the deed sits on top of it.
Where the lease is registered, the variation is then lodged with NSW Land Registry Services on a variation of lease form so the register reflects the changed terms.
Exercising an Option
An option is a right the tenant already has. It is not varied, it is exercised — by notice, in the form, manner and window the lease specifies, and often only if the tenant is not in breach.
Options are construed strictly and a late or defective notice can lose the further term outright. Where the clause as drafted will not work, the fix is to vary the option before it needs to be used.
A New Lease
Right where the changes are extensive, the premises are changing, the lease has been expired too long to be revived, or the variation would operate at law as a surrender of the old lease and the grant of a new one.
A new lease is more work than a variation, so it is worth knowing which one you are actually doing before anyone starts drafting.
The one from today’s desk
Extending an option term where both parties already agree is a textbook variation: a short deed recording the longer option, the landlord’s mortgagee consenting, and the variation registered against the lease. It is a contained piece of work — provided the title is checked, the consent is obtained and the deed is drafted so the option it creates actually works.
Traps
What Goes Wrong With Lease Variations
An Accidental Surrender and Regrant
At general law, agreeing to extend a term or to change the premises can operate as a surrender of the existing lease and the grant of a new one. That can reset guarantees, disturb priority against the landlord’s mortgagee and, for a retail lease, bring fresh obligations with it. Documenting the change as a registered variation under section 55A is one of the reasons to do it properly.
The Mortgagee’s Consent
A variation of a registered lease is not effective against the holder of a prior registered interest unless that party consented in writing before the variation was registered. In practice that means the landlord’s bank. Consent takes time, the bank usually charges for it, and a variation lodged without it can be rejected or left ineffective where it matters most.
Leaving It Until the Lease Has Ended
A variation generally cannot be registered once the lease has terminated, unless it extends the term so the lease is current again — and even then, an extension cannot be registered more than twelve months after the lease came to an end. Leases that have quietly rolled on past expiry are the ones this catches.
Assuming There Is Something to Register
If the lease was never registered there is no registered lease to vary, and the deed of variation stands on its own. That is often perfectly workable, but it changes what protection the tenant has against a new owner or a mortgagee, and it should be a decision rather than an oversight.
Retail Leases Have Their Own Rules
Under the Retail Leases Act 1994 (NSW), a retail shop lease with a term of more than three years including options must be registered, and the landlord carries the obligation to lodge it. A variation that lengthens a term or an option can push a lease over that line, and retail leases bring disclosure obligations that a commercial lease does not.
The Option You Think You Have
Exercise windows, notice methods, no-breach preconditions and the rent-setting mechanism for the further term all decide whether an option is worth anything. A variation is the natural moment to read the option properly — long before the tenant is standing at the end of the term relying on it.
How we work
How a Lease Variation Works With Us
Send Us the Lease
We start with the current lease, any earlier variations, and a short note of what the parties have agreed. Most of the time the commercial terms are already settled and we are documenting them.
Check the Title and the Lease
We search the title to confirm whether the lease is registered, who the current registered proprietor is, and what prior interests — usually a mortgage — will need to consent. We also read the clause being changed.
Review or Draft the Deed
Either we review the deed the other side has prepared and advise on it, or we draft it. Either way the aim is the same: the change is recorded clearly, the rest of the lease is left intact, and the document is capable of registration.
Obtain the Consents
We identify and request the consents the variation needs — the mortgagee’s, and a head landlord’s where the lease is a sublease. Bank consent fees and turnaround are outside our control, so we start this early and keep you posted.
Sign and Register
The parties sign the deed. Where the lease is registered, we complete the identity verification the register requires and lodge the variation electronically through PEXA and NSW Land Registry Services.
Confirm and Diarise
We confirm the variation has been registered, send you the updated title and the executed documents, and give you the dates that now matter — the new expiry, the new option window and the next review.
A straightforward lease variation is a fixed-fee service, plus disbursements. Reviewing a deed the other side has prepared and registering it is priced separately from drafting the deed ourselves. Both figures are on our pricing page and we confirm the fee in writing before we start.

Why Clients Bring Variations to Us
Fixed Fee, Quoted Upfront
A straightforward variation is priced as a fixed fee with the likely disbursements set out, confirmed in writing before we begin. No hourly meter on a two-page deed.
A Lawyer, Not a Form Service
The variation form is the last five minutes of the job. The value is in reading the clause being changed, the clauses it interacts with, and the title behind them.
Both Sides of the Lease
We act for landlords and tenants, so we know what the other side’s deed is likely to be doing and where the drafting usually favours whoever prepared it.
We Check the Title First
Registered or unregistered, who consents, whether the twelve-month window has closed. These are title questions, and they decide what document you can use.
Retail-Aware
Where the lease is a retail shop lease, we check what the change does to registration and disclosure obligations under the Retail Leases Act 1994 (NSW) rather than treating it as an ordinary commercial lease.
Registered Electronically
Variations are lodged through PEXA and NSW Land Registry Services, with identity verification handled as part of the service, so registration is not left hanging.
Have a variation to review, or one to draft? We can usually turn these around quickly.
Call TodayA variation is usually one step in a longer relationship — the lease we drafted, the option the tenant is about to exercise, the assignment when the business sells, the sale of the building with the lease attached. Because we handle leasing, conveyancing and property disputes, the variation is done with the rest of the picture in view.

Agreed the Change? Get It Documented Properly
Most lease variations arrive with the commercial terms already settled and both sides wanting it done without fuss. That is exactly the work this service is built for — check the title, confirm the right document, get the consents moving, and register the variation so the change is on the record.
